Things I've built

Track the price you actually pay — not $0.00

An App Store wishlist that tracks in-app purchase and subscription prices, the ones every other wishlist shows as $0.00 — because the price you are really waiting on lives inside the app. A server watches prices around the clock and pushes an alert when one drops, with full price history and cross-region comparison.

Know exactly how much AI you have left

A macOS menu-bar meter for your AI usage, spend, limits and resets — across Claude, OpenAI, Cursor, Codex and more. The only usage meter your AI agents can talk to, via an open MCP interface, so they can self-throttle instead of dying at a hard limit. Local-first. Buy once, use on Mac, iPhone & Watch.

Pause your webcam — without the black screen

A macOS virtual camera that freezes or loops your video feed so you can step away from a call without awkwardly going dark. Freeze a frame or loop a few seconds with smooth transitions. All processing is local — nothing leaves the device.

Look your best on every video call

A macOS virtual camera that enhances your appearance in real time on the GPU — skin smoothing, warm lighting, color grading and background blur — working as a system camera across Zoom, Meet, Teams and more. Private by design: all processing runs on-device.
